Full Radio Compatibility

32 channels (1-32), 16 groups (A-F,0-9) and Wireless ID's to remotely trigger your Godox compatible lights up to 100ft (30 meters) away. You can even wirelessly control the power of modelling lights as well.

HSS Flash Metering

You can now measure the power of HSS. No need to guess what your exposure is when using High-Speed Sync. Tell the meter your ISO and shutter speed, and it will do the rest.

Next Level Flash Analysis

Now you can easily measure the percentage of flash in your images to maintain the desired mix of ambient and flash. Measure flash duration as well to know how much stopping power your lights have to freeze sweat coming off an athlete or the flowing gown of a fashion model.

Scarlett R. ★★★★★

Installed this module in about 30 seconds, and my L-858D instantly recognized it. The radio connection to my Godox lights has been rock solid during a full wedding shoot.

Chloe F. ★★★★★

Popped this module into the battery slot next to the L-858D's cells and it seated firmly with no fiddling. Now my meter talks to the flashes without me digging for a cable, which saves a ton of time on set. The user-replaceable design is a relief since I don't have to send the whole meter in if this

Sophia ★★★★★

Finally, my L-858D can trigger my lights without a sync cord. The module slides into the battery compartment and paired instantly. It makes studio metering so much faster.
